| heal.abstract | We have produced synoptic maps from daily images of the solar corona on the disk obtained with the Nancay Radioheliograph at 169 MHz during June-August 1984. We discuss briefly the structures seen on the synoptic maps and we compare the location of radio sources with photospheric neutral lines and Her filaments derived from synoptic charts from Meudon, Boulder, and Stanford. We measured the distance of radio sources from these optical features and compared their distribution with computed random distributions. A criterion of confidence is proposed which, when applied to our data, shows that the metric radio sources of thermal origin are best associated with the large-scale neutral lines shown on the low resolution Stanford magnetograms. This association indicates that the emission comes from arcades of moderately dense loops spanning the neutral line. However, the radio sources are not usually located directly above or very close to neutral lines, but their distribution peaks at distances between 4 and 6 degrees. Our results show no statistically significant association with Meudon filaments. | en |
